Airbag control unit with part number 89170-60F20

What does the airbag control unit 89170-60F20 do?

The airbag control unit 89170-60F20 carries out control of the restraint system (SRS) in the Toyota and Lexus. It evaluates the crash sensors and, in an accident, determines within a few milliseconds which airbags and seatbelt pretensioners are triggered.

During operation it checks the unit's circuits and reports detected faults via the airbag warning light.

After an accident it stores crash data and is locked afterwards.

Why does the control unit 89170-60F20 fail?

With 89170-60F20, the most common cause after an accident is stored crash data, even if no airbag was triggered. Further causes are aged components, solder joints, moisture and voltage peaks.

Crash data remains in the unit after the accident, and an ordinary diagnostic tool cannot erase it. Airbag24 takes care of this in the repair: the crash data is erased there.

Further causes to consider:

• Aged electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage peaks, for example with a weak battery or after a jump start

How can you tell that the 89170-60F20 is defective?

A defect in the 89170-60F20 is indicated by the airbag warning light in the instrument cluster, which stays on constantly or intermittently, together with a fault message. Added to this are no connection to the diagnostic tool or a fault memory that cannot be cleared.

The warning light is the most important signal. A diagnostic tool that finds no control unit also points to a fault. As long as this is the case, airbags and seatbelt pretensioners may not trigger in an emergency.

Do not ignore such signs, because every fault message justifies a check.
